Moby eats three-sixths of a pizza. Which fraction is equivalent to three-sixths?​

Answer:

I got you! I think the answer is D. Warmer air can hold more water vapor than colder air.

Explanation:

Although this statement is true, I could be incorrect, but it is unlikely. When warm air recieves more water vapor it expands while cold air becomes packed and unstable.

Hope this helps out, good luck! (¤﹏¤)

It is so because the low air pressure create vacuum and the air from high pressure area move toward the low air pressure.

Answer:

pH = 3.34

Explanation:

We can calculate the pH using Henderson-Hasselbach's equation:

for HCOOH, pKa = 3.75.

We can calculate [HCOO⁻] and [HCOOH] using the given number of moles for each one and the final volume:

Then we proceed to calculate the pH:

The pH of the resulting solution is 3.34.

Since  

Final Volume = 44.12 mL + 250 mL = 294 mL

Now

= 294 mL / 1000

= 0.294 L

Now

[HCOO⁻] = 0.036 mol / 0.294 L = 0.122 M

[HCOOH] = 0.091 mol / 0.294 L = 0.310 M

So, the pH should be

= 3.75 + log0.122/0.310

= 3.34

hence, The pH of the resulting solution is 3.34.

C. Sebum

Explanation:

C. Sebum

Answer:

The correct answer is -

1.  a) The bubbles will shrink, some may vanish.

2. a) Can A will make a louder and stronger fizz than can B.

Explanation:

In the first question, it is given that the bottle is not opened and therefore, squeezing the bottle filled with a carbonated drink will increase the pressure on the carbonated liquid which forces the bubbles to dissolve or displace or vanish as it moves to empty space.

Thus, the correct answer would be - The bubbles will shrink, some may vanish

In the second question, there are two different conditions for two different unopened cans of carbonated water that are different temperatures one at the garage with higher temperature and one in the fridge at low temperature. As it is known that higher the temperature less will be solubility of gas in liquid so gas in can A will be less soluble which means it has more gas and it will make louder and stronger fizz than B which was stored at low temperature.

thus, the correct answer would be - Can A will make a louder and stronger fizz than can B.

Compound C8H18

mass of compound- 546.23 gram

To find:

number of moles =?

Solution:

let's find out the molar mass of C8H18= 12×8+18×1 = 114 gram/mole

Number of moles= given mass/molar mass

=546.23/114

Answer:

[IBr] = 0.049 M.

Explanation:

Hello there!

In this case, according to the balanced chemical reaction:

[tex]I_2+Br_2\rightarrow 2IBr[/tex]

It is possible to set up the following equilibrium expression:

[tex]K=\frac{[IBr]^2}{[I_2][Br_2]} =0.0110[/tex]

Whereas the the initial concentrations of both iodine and bromine are 0.50 M; and in terms of [tex]x[/tex] (reaction extent) would be:

[tex]0.0110=\frac{(2x)^2}{(0.50-x)^2}[/tex]

Which can be solved for [tex]x[/tex] to obtain two possible results:

[tex]x_1=-0.0277M\\\\x_2=0.0245M[/tex]

Whereas the correct result is 0.0245 M since negative results does not make any sense. Thus, the concentration of the product turns out:

[tex][IBr]=2x=2*0.0249M=0.049M[/tex]

Answer:

Explanation:

Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This allows the water molecule to become attracted to many other different types of molecules.

Which set of orbitals are degenerate?

Degenerate is used in quantum mechanics to mean 'of equal energy. ' It usually refers to electron energy levels or sublevels. For example, orbitals in the 2p sublevel are degenerate - in other words the 2px, 2py, and 2pz orbitals are equal in energy, as shown in the diagram.

Explanation:

Answer: 1.825 moles of hydrogen gas are produced.

Explanation:

The balanced chemical equation is:

[tex]Mg(s)+2HCl(aq)\rightarrow H_2(g)+MgCl_2(aq)[/tex]  

According to stoichiometry :

2 moles of [tex]HCl[/tex] require = 1 mole of [tex]Mg[/tex]

Thus 3.65 moles of [tex]HCl[/tex] will require=[tex]\frac{1}{2}\times 3.65=1.825moles[/tex]  of [tex]Mg[/tex]

Thus [tex]HCl[/tex] is the limiting reagent as it limits the formation of product and [tex]Mg[/tex] is the excess reagent.

As 2 moles of [tex]HCl[/tex] give = 1 mole of [tex]H_2[/tex]

Thus 3.65 moles of [tex]HCl[/tex] give =[tex]\frac{1}{2}\times 3.65=1.825moles[/tex]  of [tex]H_2[/tex]

Thus 1.825 moles of hydrogen gas are produced.

Answer:

2365 g

Explanation:

The mass of CaCl₂ will be 110.98 grams, this can be calculated by using the molarity formula.

It is defined as the ratio of a number of moles of solute to the volume of solution in liters.

It is given by:

M= n/V

What information do we have?

V= 1.0 L

M= 1.0 M

Molar mass of CaCl₂  = 110.98g/mol

To find:

m=?

M= n/V

n= M/V

n= 1 mole

A Number of moles is the ratio of mass over the molar mass.

n = m/ M

1 mole= m / 110.98 g/mol

m= 110.98 grams

Thus, the mass of calcium chloride is 110.98 grams.

Answer:

a) 0.099 L

b) 9.9

Explanation:

Now, given the equation for the decomposition of H2O2;

2H2O2(l) ------> 2H2O(l) + O2(g)

Mass of H2O2;

percent w/v concentration = mass/volume * 100

volume = 10.0-mL

percent w/v concentration = 3.0 percent

mass of  H2O2 = x

3 = x/ 10 * 100

30 = 100x

x = 30/100

x = 0.3 g of H2O2

Number of moles in  0.3 g of H2O2 = mass/ molar mass

Molar mass of H2O2 = 34.0147 g/mol

Number of moles in  0.3 g of H2O2 = 0.3g/34.0147 g/mol

= 0.0088 moles

From the reaction equation;

2 moles of H2O2 yields 1 mole of oxygen

0.0088 moles of H2O2 = 0.0088 * 1/2  = 0.0044 moles of oxygen

If 1 mole of oxygen occupies 22.4 L

0.0044 moles of oxygen occupies 0.0044 *  22.4/1

= 0.099 L

b) initial volume of the H2O2 solution = 10 * 10-3 L

Hence, ratio of the volume of O2 collected to the initial volume of the H2O2 solution = 0.099 L/10 * 10-3 L = 9.9

Explanation:

The molecular formula for Guanylate is [tex]\mathbf{C_{10} H_{14} N_5O_8 P}[/tex]

This is calculated by the addition of the atomic weight of all the atoms taking part in the molecule.

i.e. (10 × C) +  (14 × H) + (5 × N) + ( 8 × O) + (1 × P)

= (10 × 12) +  (14 × 1) + (5 × 14) + ( 8 × 16) + (1 × 30)

= 120 + 14 + 70 + 128 + 30

= 362 g/mol

The diagram for the tautomers of hypoxanthine can be seen in the image attached below.

Dihydrouridine is available and can be seen in tRNAs and rRNAs. It is an exceptionally preserved and adjusted base. It is a pyrimidine nucleoside that is shaped by the expansion of two hydrogen atoms to uridine. By the expansion of two hydrogen atoms to uridine makes it completely soaked and no presence of any two-fold or double bond.  

Catalytic reduction of carbon-carbon double bonds in Dihydrouridine synthase occurs at positions 5 and 6 on the uridine base.  

Hence, 5 and 6 carbon particles inside the uracil moiety of this nucleotide have two hydrogens each connected to them.

Which answer would represent 0.001 moles?

Answer:

See explanation.

Explanation:

Hello!

In this case, according to the thermodynamic definition of the Gibbs free energy:

[tex]\Delta G=\Delta H-T\Delta S[/tex]

In the scenario by which G>0 (nonspontaneous) it would be possible for reaction to have a G<0 (spontaneous) if:

- If H>0 and S>0, then the temperature should be increased until the process was entropy-driven for it to be possible.

- If H> and S<0, then it'd be impossible to have an spontaneous process.

- If H<0 and S>0 then the process was not spontaneous.

- If H<0 and S<0 it is possible if the temperature is not high enough to ensure the process is enthalpy-driven.

Answer:

720 divided by 2 answer is 556 so answer per is 3.32.3

Explanation:

The force of gravity points straight down, but a ball rolling down a ramp doesn't go straight down, it follows the ramp. Therefore, only the component of the gravitational force which points along the direction of the ball's motion can accelerate the ball. The other component pushes the ball into the ramp, and the ramp pushes back, so there is no acceleration of the ball into the ramp. If the ramp is horizontal, then the ball does not accelerate, as gravity pushes the ball into the ramp and not along the surface of the ramp. If the ramp is vertical, the ball just drops with acceleration due to gravity. These arguments are changed a bit by the fact that the ball is rolling and not sliding, but that only affects the magnitude of the acceleration but not the fact that it increases with ramp steepness.
